Polyurethane Waterproofing Injection Grout
MVX Hydro-PolyGel is designed for injection of joints or repairing leaks in concrete structures. In contact with water, it forms a flexible gasket in crack or joint. Corrosive environments will not affect the performance.
The system is ideal for movement of the substrate in excess of 10%. The resin expands and cures to a resilient, flexible closed-cell foam when in contact with water. MVX Hydro-PolyGel will not be easily washed out in case of high volume water flow. After injection it will react with water and fill voids, cut off active water leaks, seal potential water leaks and stablise coarse materials.
MVX Hydro-PolyGel is designed to withstand wet-dry cycles and thermal movements. It cures to form a hydrophilic flexible foam.
AREA OF USE
For sealing of water ingress between concrete tunnel segment joints
Screen injections behind tunnel segments
For sealing moving, leaking cracks
For waterproofing man and non-man accessible sewer pipes
For sealing of expansion joints
Used as a 1-component system for wet, non-structural cracks
Used as a 2-component system with a 1:1 ratio water for sealing dry, moving and non-structural cracks
